Claims..

The present invention relates to the art of wrapping andlabellingarticles of merchandise, and more particularly to the application oflabels, bands or other indicia bearing means to such 5 articles as areenclosed in a Wrapping material the overlapping edges of which areadapted t0 be sealed or welded together by the application of heat.

It is customary to wrap or otherwise enclose known articles ofmerchandise in a protective Wrapper, such, for example, as waxed paper.It is also customary to print identicaton and/or advertising indicia onsuch material prior to waxing the paper, or, alternatively, to place arelar"tively narrow strip or band of similar material,

bearing the desired indicia, on or about the wrapper after an article ofmerchandise has been enclosed therein. f

Recently, there has come into extensive use for 20 wrapping purposes,several kinds of transparent,

non-fibrous, cellulosic sheet materials. The moistureproof varieties ofthese materials are preferable to a waxed paper Wrapper by reason oftheir more complete transparency, higher moistureproofness, toughnessand their ease of sealing upon the application of heat and pressure.

The printing of the moistureproof variety of this transparent,non-fibrous, cellulosic sheet material necessitates the use of inkscontaining 30 organic solvents. Therefore, in the process of printingwith such inks, the material, as it leaves the printing press, is passedthrough a heating zone to dry the ink, both to prevent oisetting and toevaporate the ink solvent. In the roll form 35 in which this printedmaterial commonly is supplied to the market, the odor of the residualprinting ink solvent persists for long periods of time. Inasmuch as thisodor is highly objectionable, particularly in wrappers for edibles, itbecomes necessary to heat the material again, prior to its entry intothe wrapping machine proper, in order further to dry out the printingink and dispel its odor.

However, it is Well known that when this moisture-proofed, non-fibrouscellulosic sheet material is freely subjected to heat, as in the processof drying the printing ink, certain of its desirable characteristics aregreatly impaired, if not enr tirely lost. For example, when heat isapplied as above mentioned, the iiexibility, tensile strength,

moisture-proofness and heat-sealing characteristie of the material are4adversely affected to a substantial extent.

Also, it is known that the cost of printing a Wider sheet of suchaforesaid material is substantially greater than the cost of printingthe same matter on a relatively narrower sheet. Further, as the indiciacustomarily occupies only a small portion of the sheet, there is nonecessity oi' passing the entire web through the press and 5subsequently heating the sheet in its entirety. As the material whichhas undergone printing and drying deteriorates more rapidly by reasontherer of, it follows that va great waste and expense results when thusit has been rendered unsuited 10 for use.

It is the primary object of my invention to provide an improved wrappercomprising indicia in connection with transparent wrapping material ofthe type describedwhich will obviate the above noted disadvantages andobjections.-

A further object of my invention is to provide indicia in associationwith this type of transparent wrapping material in a manner such thatthe expense of wrapping articles of merchandise therein Still anotherobject of my invention is to provide an indicia bearing member adaptedto be associated with a transparent wrapping material whereby thenecessity of printing indicia directly on the wrapping material iseliminated.

' It is a further object of my invention to provide an indicia bearingmember adapted to be associated with a transparent wrapping materialwhereby the indicia carried by said member will appear as if beingcarried by the wrapping material itself and whereby the indicia bearingmember will lose its identity in that of the wrapper.

Another object of my invention is to so combine an indicia bearingmember with the wrapping material'that the indicia bearing member isapplied to an article of mechandise in an improved way during thewrapping operation.

And another object of my invention is to provide an improved combinationof wrapper and 40 indicia bearing member of the type heretoforedescribed which will be economical of manufacture, which may be easilyand efciently applied to articles of merchandise and which, when onceapplied, cannot be easily separated without attracting attentionthereto.

In accordance with my invention, I provide the desired indicia, such asidentifying characters, advertising matter, etc., on a relativelynarrow, transparent band after the manner shown, for example, in U. S.Patent No. 1,818,923. This transparent band is, preferably, of the sametransparent material as is employed in wrapping the articles ofmerchandise, the wrapper, however, being entirely free from any printingor strength of the transparent wrapper with which it is associated. And,in order to insure the retention of the band and its wrapper in apredetermined relation, I apply a thin layer of transparent adhesivebetween the band and the wrapper, either in a continuous strip or atsuitable intervals disposed longitudinally of said band, the adhesiveserving, also, to retain the band suitably rolled up when rolled on aroller for vstorage prior to combining it with the wrapping roll.

The novel features of my invention are set forth with particularity inthe appended claims. The invention itself, however, both as to itsorganization and method of application. together with additional objectsand advantages thereof,

will best 'be understood from the following description of severalspecific embodiments when read in connection with the accompanyingdrawings, in which y Figure 1 is a view, in perspective, showing a loafof bread wrapped ina sheet of transparent wrapping material havingassociated therewith an indicia bearing band in accordance with myinvention,-

Figure 2 is a. sectional view taken on the line 2-2 of Figure l,

Figure 3 is a bottom plan view showing one way in which the indiciabearing band may be applied to the wrapper sheet in accordance with myinvention,

Figure 4 is a plan view of the transparent indicia bearing band withspots of adhesive applied to the upper side thereof, and

Figure 5 is a view in side elevation illustrating one manner in whichthe band and wrapper may be combined.

Figure 6 is a bottom plan view showing another way in which theindicia-bearing band may be applied to the wrapper sheet in accordance,with my invention.

Figure 7 is a pian view of the transparent indicia-bearing band with theadhesive material applied to the upper side in the form'of short narrowlines.

Figure 8 is asectional view of a loaf of bread enclosed in atransparent, non-fibrous wrapping material with an indicia bearing bandapplied on the outside of the wrapper.

Referring to the drawings, wherein similar reference numerals indicatecorresponding parts throughout, I have shown a loaf of bread 1,representative of any article of merchandise, completely enclosed in atransparent wrapper of nonfibrous cellulosic material 2 which hasmoisture proof qualities and the overlapping edge portions 3 of whichcan be sealed together by the application of heat and pressure thereto.Encircling the loaf 1 is a relatively narrow sheet or band oftransparent material 4 having applied thereto, upon one surface thereof,as by printing, suitable indicia 5, such as advertising matter or thelike. Preferably, the band 4 is of the same material as the wrapper 2and is disposed between the loaf l and the wrapper 2 so that the band 4will be practically invisible as an entity and so that its own identitywill be substantially lost in that of' the wrapper. Preferably, also,the surface of the band 4 to which the indicia 5 has been applied isnext adjacent, or in contact with, the inner surface of the wrapper 2.Thus. although the band 4 cannot, except on close scrutiny, be discernedapart from the wrapper 2, the indicia 5 thereon can readily be seen andread, and it appears to be applied directly on the wrapper itself.

The wrapping material 2 and the band 4 may be applied to the loaf 1simultaneously, being fed to a suitable automatic wrapping machine (notshown) from the rolls 2a and 4a. respectively. In some cases, it may bedesirable to combine the wrapper 2 and the band 4 at the paper mill inthe manner shown in Figure 3 before supplying customers therewith. Inother cases, however, it maybedesiredtorollthewrapperZandtheband 4 onseparate rolls to be combined just prior to being fed to the wrappingmachine, as illustrated in Figure 5. In either case, since the two areultimately united into a unitary structure, it is essential that somemeans be provided for combining the two in a predetermined relation andfor retaining them in this relation.

For this purpose, I provide, on'the band 4, an adhesive 6 whicheifectively unites the band 4 with the-.wrapper 2. The adhesive shouldbe transparent, preferably have the same index of refraction as thewrapper 2 and the band 4 to avoid contrast therewith, and may be appliedto the band 4 in the form of a continuous strip 6 positioned adjacentand running parallel to the longitudinal edges of the band as shown inFigure 6, or, and preferably, in the form of a plurality of spots atspaced intervals. These spots may be applied in two sets, one along thelongitudinalv edge 'I of the band, and the second set along thelongitudinal edge 8 of the band. When the wrapper 2 and the band 4 withthe adhesive spots 6 thereon are brought into contact in a predeterminedrelation and under pressure, as by passing through the 'rollers 10, l0,they are securely united together and their relative displacementthereafter is prevented. Thus, there is no danger of the band slippingand being improperly applied to the loaf 1 when, as in the wrapping andsealing operation, the wrapper and band are placed under tension.

'Ihe spots 6 may have any desired configuration, but I prefer to providethem in the form of small triangles, rhomboids, diamonds, circles,and/or short, narrow lines as illustrated in Figure 7. I also prefer toso locate them that the spots of one set on the band 4 will be instaggered relation with respect to the spots of the other set. While theadhesive spots 6 serve` in the case where the band 4 is rolled up byitself, to securely retain the band in convoluted form, it is essentialthat the rolled-up band be capable of free unwinding so that it can befreely supplied to the wrapping machine in association with the wrapper2. If the proper adhesive is chosen and it is applied in the mannerheretofore described, the staggered spots, terminating in points (or, atleast, tapering oi!) in the direction in which the roll is unwound,permit free. unwinding thereof while still retaining suillcienttackiness to unite the band with the wrapper. For this purpose, theadhesive obviously must be of a permanently tacky, non-drying type.

From the foregoing description, it will be apparent that I have provideda method of applying indicia in connection with a package wrapped intransparent cellulosic material without subjecting the package to thedisadvantages of the prior art. By applying the indicia on the band 4instead of on the wrapper 2, the contaminating odors of the printing inkmay be entirely removed without in any way aecting the moisture proofqualities of the wrapper, while the fact that the band 4 may have beenweakened is quite immaterial.

Although I have shown and described certain specic embodiments of myinvention, I am fully aware that various other modifications arepossible. For example, it is possible to apply the band 4 on the outsideof the package as illustrated in Figure 8 instead of within the wrapper2, in which event the indicia and the adhesive are applied to the undersurface thereof. My invention is not to be limited, therefore, exceptinsofar as is necessitated by the prior art and by the spirit of theappended claims.
